Find the solution to the system:
Sliva [168]

Answer:

u = 12, v= 15

Step-by-step explanation:

Given the system of simultaneous equation:

1/6 u− 1/3 v=−3... (1)

0.2u+0.1v=3.9...(2)

Rewriting both equation as fraction

1/6 u− 1/3 v=−3

1/5 u + 1/10 v = 39/10

Multiplying equation (1) by 6 and (2) by 10 we have:

u - 2v = -18... (3)

2u + v = 39...(4)

Using elimination method, we will first multiply equation (3) by 2 and (2) by 1 to have:

2u-4v = -36 ...(5)

2u+v = 39...(6)

Subtracting (5) from (6);

-4v-v = -36-39

-5v = -75

v = -75/-5

v = 15

Substituting v = 15 into equation (3) to get u we have:

u - 2(15) = -18

u - 30 = -18

u = -18+30

u = 12

The solution to the system of simultaneous equation are u = 12 and v = 15

HELP ME WITH NUMBER 1 PLEASE!!!!!
Sonja [21]

Answer:

x > 367

Step-by-step explanation:

set x = # of DVDs they sold

Each DVD costs $15 so the total amount they made is 15x

Since they raised more than $5500

15x > 5500

Divide both sides by 15 to solve the inequality and you get

x > 366.67 and since you can't sell 0.67 of a DVD, round up to get

x > 367 which means that they sold more than 367 DVDs
